The purpose of this guide is to provide a reference for the selection of relay schemes and to assist less experienced protective relaying engineers in applying protection schemes to transmission lines.
However, for protection of the turbine, underfrequency relays are generally required unless the turbine manufacturer states that this protection is unnecessary.
Proper Design & Engineering A substation must have complete engineering and design documents, such as: Single Line Diagram (SLD) Layout drawings Protection & control drawings Cable routing
